Take our classic Nano Puff Pullover, add a full-length zipper for greater all-around ease and, presto, the Nano Puff Jacket – an insulated jacket in spring squalls, a sleek micro-belay parka on chilly rock routes and a thermal midlayer all in one. The wind-blocking,100% recycled polyester shell sheds moisture and also glides effortlessly between layers. Low-bulk, hydrophobic, highly compressible PrimaLoft ONE (60-g) insulation traps heat with remarkable efficiency, even when wet. The jacket has a shaped fit and the soft, wicking interior storm flap and zipper garage adds chin comfort when zipped up. Its internal zippered chest pocket doubles as a self-stuff sack with a carabiner clip-in loop. It also has two zippered handwarmer pockets, elasticized cuffs and a dual-adjust drawcord hem to seal out wind and seal in warmth.

This is a great lightweight jacket that can be worn by itself or layered under a soft-shell jacket for extra warmth or protection from the elements. Packs down really small in it's own pocket so there's no fear that it will take up too much space in your pack or luggage.

I bought this for my husband after previously buying the women's version for myself. He loves that it is lightweight, looks great, and fits him well. You would never guess that a jacket this light could be so warm!

The Nano Puff series rocks hard! It's like wearing a sleeping bag all day long when the weather drops. I've taken this jacket on many camping, bike packing, back packing, and fishing trips. It packs down so small that you can take it anytime or any where when space is limited. It's an essential piece for all my adventures. Get one! You won't be disappointed.

First off, I love this jacket. I had my eye on it for a year and finally the hints gave way to a gift. This jacket is extremely comfortable and light. I have replaced my fleece with this jacket and love that it does not feel bulky in the slightest bit. I use it for day hiking/camping and general around town activities. The only drawback I have seen is it's durability. It is obvious it was designed for occasional use and not daily wear. The stitching is questionable and after only 2 months of wear the stitching is giving in some areas. I'll admit I have used it daily as my go to jacket but the stitching could be stronger. use with caution and enjoy. Again, I love the jacket and recommend it but use it carefully for it to last.

Had to exchange LG for XL as fit everywhere except shoulders & underarms. Now seems to fit too loose for body taper & sleeve length but still is an amazing jacket. Have worn it under a cycling windbreaker & rode in +20F comfortably. I like that it zips for overheat/moisture control but now w/ extra length zipper bunches at end & takes two hands to operate without catching. But... have experienced down & would never use it again for moisture prone & quick drying needed activities! I would suggest all those w/ larger arms, necks & shoulders but still a more normal (shorter?) body build find a local place to try before ordering. Works incredibly well w/ a wool vest too!
